The invention relates to golf clubs. More particularly, the invention provides methods and systems for analyzing performance characteristics of a golf swing.
Golf swing analysis clubs and systems exist for measuring characteristics of a golf swing. Existing systems typically include sensors attached to a golf club or external components. The system shown in U.S. Pat. No. 6,441,745, for example, shows a transmitter attached to the shaft of a club and an external head speed sensor that is placed on the ground behind a golf ball. Some of the drawbacks of the system shown in U.S. Pat. No. 6,441,745 are that the transmitter affects the aerodynamics of the golf swing and the required use of an external head speed sensor limits the usability of the system.
Some golf swing analysis systems include removable memory modules. The removable memory module stores golf swing characteristic information and provides the information to a computer after a period of analysis. One drawback of these systems is that they do not provide real time feedback to the golfer. For example, if the removable module stores information during a round of golf, the information is not provided to the golfer until after the round of golf when the memory module is removed and connected to a computer device. As a result, the golfer cannot use the information during the round of golf.
Other golf swing analysis systems include wiring harnesses connecting a golf club to a computer or display device. Because of the restrictions in range of motion imposed by such systems, they are not practical to use on an actual golf course.
Therefore, there is a need in the art for portable golf swing analysis clubs and systems that can be used on a golf course without bulky external equipment and that provide real time feedback to a golfer.
One or more of the above-mentioned needs in the art are satisfied by the disclosed golf clubs and golf swing analysis systems. The disclosed golf clubs may be self contained and include sensors and transmitters located within the golf clubs. As a result, the golf clubs can be used during a round of golf and do not interfere with the golfer. In certain embodiments, the disclosed golf clubs wirelessly transmit golf swing characteristic data to a portable device, such as a personal digital assistant (PDA) or watch.
In a first embodiment of the invention, a self contained instrumented golf club is provided. The golf club includes a first accelerometer module mounted in a head of the golf club and a second accelerometer module mounted in a shaft of the golf club.
In a second embodiment of the invention, a user interface for displaying golf swing performance information of a golfer is provided. The user interface includes a first section displaying a measured first golf swing parameter at a location along a bar graph to indicate a relationship between a value of the measured first golf swing parameter and a preferred value of the first golf swing parameter.
In yet another embodiment of the invention, a method of providing golf swing data to a golfer is provided. The method includes receiving golf swing data from a self contained instrumented golf club and displaying in real time, on a portable computer device, at least some of the golf swing data in relation to preferred golf swing data.
In other embodiments of the invention, computer-executable instructions for implementing the disclosed methods are stored as control logic or computer-readable instructions on computer-readable media, such as an optical or magnetic disk.
The present invention is illustrated by way of example and not limited in the accompanying figures in which like reference numerals indicate similar elements and in which:
System 100 may also include a weight distribution module 130 for measuring a golfers weight distribution during a golf swing. In one embodiment weight distribution module 130 is implemented with sensors placed within the golfers shoes. The sensors may include strain gauges, conductive ink, piezo-electric devices and/or pressure transducers. The relative pressure applied to each sensor can be used to indicate weight distribution. Weight distribution module 130 also preferably includes a transmission module for wirelessly transmitting data to portable computer device 120.
A head 208 of golf club 200 may include an impact module 210 for measuring the impact of a golf ball relative to the face of head 208. Impact module 210 may include a strain gauge. Head 208 may also include a removable accelerometer module 212. Accelerometer module 212 may include a three-axis accelerometer for head measuring acceleration along three orthogonal axes. Embodiments that include a removable accelerometer module, as opposed to embodiments that include a module embedded into head 208, provide certain advantages. For example, a single removable accelerometer module may be used for several different clubs and allows a golfer to upgrade or replace the accelerometer module without replacing the entire club.
Data from all of the sensors may be sent to a transmission module 214. Transmission module 214 may be configured to transmit data via an antenna to portable computer device 120 (shown in
In one embodiment of the invention, all of the sensors are located within golf club 200 so as to not interfere with the aerodynamics of the club. Golf club 200 may also be configured so that the weights of the included components do not change the balance or center of gravity of the club. Golf club 200 may be a wood, iron, putter or specialty club.
One skilled in the art will appreciate that numerous additional sensors may be used in connection with aspects of the invention.
When electromagnetic sensors are used, club head speed may be determined by measuring the Doppler frequency shift of waves reflected from a ball 306. Golf club head 304 or another part of the golf club may include a module for determining the Doppler frequency shift. Impact location may be determined by measuring the phase shift of reflected signals from ball 306 just prior to impact, such as 15 cm prior to impact. A frequency of 2 GHz may be used for a wavelength of 15 cm. The phase shifts correspond to distances. The accuracy of the determination of the impact location may be increased by using more sensors. In one embodiment three sensors are used for determining impact location. Swing tempo may be determined by using the sensors as proximity sensors. For example, the sensors may be used to determine when golf club head 304 is in close proximity to ball 306 just prior to back swing and then before impact. The time period between the two measurements corresponds to the swing tempo.
Ultrasound sensors may function in a similar manner. A number of ultrasound sensors, such as 2-5 may be attached to or embedded in the head of a golf club. Club head speed may be determined by measuring a frequency shift in a signal reflected from a ball. For example, with a transducer of 40 kHz, a club head speed of 130 mph would result in a 70 kHz reflection. A number of ultrasound sensors placed around the face of the club, such as two along each side and one on the top, may be used to determine impact location. The time of flight of each signal just prior to impact corresponds to the distance between the ball and the sensor. The individual distances may be used to determine impact location. Ultrasound sensors may also function as proximity sensors to determine swing tempo in the manner described above.
In alternative embodiments, electromagnetic or ultrasound sensors may be placed in or attached to a golfer's shoes to perform the functions similar to those described above. The sensors detect movement of the club head which can be used to determine golf swing parameters.
The earth's magnetic field may also be used to determine golf swing parameters. Magnetic field sensors may be attached to or embedded within a golf club to detect components of the earth's magnetic field at different club locations. As shown in
The club head face angle may be determined by first taking a reference measurement of the magnetic field before the back swing and then taking another measurement of the magnetic field just prior to impact. For example, the magnitude of component vectors 406, 408 and 410 will have first values before the back swing and second values just prior to impact. The different component vector values can then be used to determine the face angle. If the magnetic field in the x-y plane is assumed to be 0.3 Gauss, the component X of the field with respect to component vector 408 (x axis) is determined by X=0.3 cos θ and the component Y of the field with respect to component vector 410 (y axis) is determined by Y=0.3 sin θ.
A 1 degree difference would cause a change in the magnitudes of vector components 408 and 410 as follows:
The smallest change that needs to be detected along each vector component may be determined by taking the derivative of each component and determining were the derivative crosses the 0 axis.
dX/dθ=−0.3 sin θ=0 at θ=0 degrees
dY/dθ=0.3 cos θ=0 at θ=90 degrees
The highest resolution in the x-component is needed when the angle rotates from 0 to 1 degree and corresponds to 45.7 μG. The same resolution is needed when the y-component rotates from 89 to 90 degrees.
Swing tempo may be determined by using vector component 406 (z axis) as a tilt sensor. A reference measurement of vector component 406 may be recorded before the back swing. The period required for the club head to return to a position such that the vector component 406 returns to the measured reference value corresponds to the swing tempo. In an alternative embodiment, velocity information may also be just to determine impact time and the resulting swing tempo.
Several different measurements may be used to determine the swing path.
Gyroscope 602 may be used to determine golf swing parameters by assuming that the point of rotation is a golfer's shoulders. Club head velocity may be determined by an accelerometer that is part of the same MEMS, an external accelerometer or some other device. For golf swing parameter determination purposes, in the proximity of a ball the movement of golf club head 604 may be modeled as an object moving on the surface of a sphere. The sphere has a radius equal to the length of the club plus the length of the golfers arms. In one embodiment, a standard radius of 62.5 inches is used. In other embodiments, a golfer may provide his or her arm length and/or club length for more accurate determinations.
The face angle of golf club head 604 may be determined as a function of the shaft rotation rate. The shaft rotation rate may be determined by gyroscope 602.
The face angle is then determined by adding the face angle change to the original face angle in step 710.
Club head speed may be determined as a function of the radius (arm length plus club length) and angular velocity. In particular, the club head speed is the product of the radius and the angular velocity of golf club head 604.
Swing tempo may be determined by first determining when the angular rate is zero and begins to increase at the start of the back swing. The time of impact may then be determined by a spike in the angular rate that accompanies the impact or from one or more other sensors, such as an accelerometer or impact sensor.
Rotational velocities may also be used to determine the swing path. In one embodiment in which gyroscope 602 is implemented with a three axis gyroscope and in which the z-axis is used to determine changes in face angle, the y-axis is used to determine motion in a target reference plane and the x-axis is used to determine motion parallel to the target reference plane, the swing path may be estimated by the following formula:
A grip pressure bar 808 may be included to display grip pressure relative to an optimal value. A shaft energy transfer bar 810 may be included to illustrate the deviation of shaft energy transfer from a predetermined optimal value. Shaft energy transfer is a function of the distance of the club head relative to the club shaft centerline. In one embodiment of the invention, accelerometer module 204 may be used to determine a location of the club shaft and accelerometer module 212 may be used to determine the location of the club head. The distance between the club head and club shaft centerline just prior to impact with the golf ball may be used to determine shaft energy transfer. Relative club speed and weight transfer may be displayed with menu bars 812 and 814 respectively. Weight transfer is defined as a percentage of weight that is transferred from the rear foot to the front foot during a golf swing. Of course numerous additional or alternative variables may be detected by sensors that are a part of golf club 200 (shown in
Next, in step 906 the golf swing data corresponding to the preferred golf swing is stored as preferred golf swing data. The preferred golf swing data may include values of variables such as tempo, grip pressure, shaft energy transfer, club speed, club face angle, swing path, impact location and weight transfer. The preferred golf swing data may later be used as a reference when analyzing other golf swings. For example, after hitting a drive that the golfer wishes to use as a reference, a club head speed of 125 mph that was measured during the swing may be stored as a preferred value. That is, the preferred value of the club head speed parameter would be set to 125 mph. In step 908 the portable computer device may receive golf swing data from a self-contained instrumented golf club. The self-contained instrumented golf club may be similar to the golf club described above and the golf swing may be a golf swing made during an actual round of golf. The portable computer device may also receive weight transfer data from a weight transfer module in step 910. The data received in steps 908 and 910 may be received using one of the wireless transmission methods and protocols described above.
In step 912 at least some of the golf swing data and weight transfer data is displayed in real-time on a portable computer device in relation to preferred golf swing and weight transfer data. Step 912 may include displaying the data on a user interface such as the user interface shown in
One skilled in the art will appreciate that aspects of the present invention may be used in connection with several different user interfaces.
After selecting a particular entry with graphical user interface 1004, a golfer may then be presented with a graphical user interface that displays baseline golf swing parameters.
Graphical user interface 1302 includes a grid overlying the face of a golf club. Numbers may be added to regions to indicate the number of times the regions corresponded to impact location. For example, region 1304 corresponded to the impact location during two golf swings. A data selection region 1306 may be included to allow the golfer to view other golf swing parameter values.
While the invention has been described with respect to specific examples including presently preferred modes of carrying out the invention, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques that fall within the spirit and scope of the invention as set forth in the appended claims.
